Patent CA-2270131-A1 (CA)
Inventor: SMITH NIGEL PETER
IPC: A61L9/12
Filed: 1997-10-22
Abstract: L'invention concerne un procédé et un appareil, qui servent à disperser dans l'air un agent modificateur d'air (tel qu'un parfum). L'agent modificateur d'air et une électrolyte sont entraînés dans un réservoir (7) aqueux à base gel, qui est au contact de deux électrodes (8, 9), l'une étant chargée positivement, l'autre négativement, de façon à fournir un courant électrique entre les deux électrodes. Le courant électrique alimente un petit moteur (14) de ventilateur (13), lequel disperse dans l'air ambiant l'agent modificateur d'air provenant de la surface du réservoir (7), via des orifices (16) pratiqués dans un logement (10) de l'appareil. Le courant électrique peut alimenter des dispositifs électriques supplémentaires ou complémentaires, tels des dispositifs d'éclairage ou de chauffage. L'ensemble peut être conçu de sorte que la vitesse d'épuisement de l'agent modificateur d'air contenu dans le réservoir (7) corresponde généralement à la vitesse d'épuisement des électrodes (8, 9), la façon dont fonctionne le dispositif électrique indiquant la présence de l'agent modificateur d'air dans le réservoir (7).

Abstract: Mobile station radio communication equipment MS is provided with a transmission-reception amplifying section AMP, a radio communication section TRX, a base-band signal processing section BB, a mobile station control section MS-CNT, and a terminal interface section TERM-INT. In multi-code transmission, the availability of a frequency resource and communication quality are improved by transmitting control information (pilot symbol and TPC symbol) only with one designated individual physical channel boosted in electric power. In addition, the availability of the frequency resource and communication quality are improved and, at the same time, the power consumption is reduced by deciding the transmission/cancellation of transmission information in accordance with the communication quality and communication state. Moreover, the availability of the frequency resource is improved and the power consumption is reduced by avoiding the occurrence of frequent calls.

Title: Downhole oil-sealed bearing pack assembly
Inventor: BESHOORY EDWARD JOSEPH
IPC: E21B4/00
Filed: 1999-08-18
Abstract: A downhole oil-sealed bearing pack assembly is provided for protecting bearing elements and seals. The bearing pack assembly includes a non-contact flow restrictor for reducing large differential pressures across sealing elements.  The non-contact flow restrictor includes an inner restrictive element attached to a rotatable drive shaft and an outer restrictive element secured to a stationary bearing housing. The inner restrictive element can include an outwardly extending ring adjacent to a first land and the outer restrictive element can include an inwardly extending ring adjacent to a second land. During rotation of the drive shaft the inwardly and outwardly extending rings remain a distance from the second and first lands, respectively, thus permitting a fluid to traverse the rings and lands. The invention also provides a wear sleeve for increasing seal and shaft life. The wear sleeve includes a groove cut into a hollow sleeve which is secured to the rotatable driveshaft. A cooling fluid within the groove dissipates heat generated by seals contacting the wear sleeve on the rotating shaft. Further, a piston and dipstick assembly is provided for supplying oil to bearing elements and for measuring oil within a reservoir. The piston and dipstick assembly includes a chamber for containing oil and a drilling fluid. A floating piston applies pressure to the oil in the chamber and prevents the drilling fluid from mixing with the oil. A conduit extending into the chamber permits a dipstick to measure the location of the piston within the chamber to determine the amount of oil remaining within the chamber.

Abstract: The invention concerns a closure for a cylindrical can (10). The closure includes a flexible member (11) of the easy-open type secured across the open end of the can (10). A rigid, screw cap (22) is screwed over the thus sealed end of the can. An annular, resilient member (24) depending downwardly from the underside of the end wall of the cap (22), engages the membrane (11) in the vicinity of the end flange (18) of the can body (10), thereby strengthening the seal between the membrane (11) and the flange (18). This advantageously permits cooking of the contents of the can with the flexible membrane (11) in situ, thereby giving rise to a can having an easy-open end, the contents of which can are cooked and sterilized using conventional processing lines.

Title: Method for unwinding rolls of paper
Inventor: KEWIN DANIEL D
IPC: B65H75/18
Filed: 1997-09-05
Abstract: A method of mounting narrower paper rolls for unwinding on a pair of stub chucks spaced for mounting and unwinding full width paper rolls and carried by arms of a pair of multiple reel stands includes providing a narrower paper roll wound on a tubular core assembly having a hollow cylindrical core member and an annular end member of metal or plastic within each opposite end portion of the core member. The end members are removed from the core member, and the core member is mounted at a desired longitudinal location on a full length shaft having opposite ends engageable with said stub chucks. Core member engaging devices are provided to enable the core member to be secured in said desired longitudinal location and to transmit rotational torque from the shaft to the core member. The full length shaft with the narrower paper roll thereon is then mounted on the stub chucks. A narrower paper roll can thus be mounted on multiple reel stands whose stub chucks are spaced for full width paper rolls without interrupting the unwinding operation of another paper roll mounted on the multiple reel stands.

IPC: A47J37/08
Filed: 2000-03-31
Abstract: An improved contact toaster for heating bagels, muffins and other food items features a housing containing a toasting chamber with an inlet and an outlet. The toasting chamber contains a pair of conveyor belts with a removable platen positioned between them. Two auxiliary heaters are positioned so that they heat both the platen and the conveyor belts. A pair of tensioners engage the conveyor belts so that pathways between the conveyor belts and platen taper inward to a minimum thickness and then expand outward again. As a result, food items moving through the pathways via the conveyor belts are toasted on both surfaces and also absorb heat from both the platen and the conveyor belt surfaces as they are compressed and released. The platen may be diamond shaped to increase the rate and degree of compression and release and removable so that thicker food items may be accommodated. The platen may contain upper and lower heating elements that may be individually controlled to provide greater heat in the region of maximum compression of the food item.
